ROTARY HEEEL-TRl MM ER.

SPECIFICATION forming part of Letters Patent No. 328,853, dated October 20, 1885. Application filed May 6, 1885, Serial No. 164,591. (N 0 model.)

To all whom it may concern:

Be it known that I, J AMES L. LORD, of Lynn, in the county of Essex and State of Massachusetts,have invented certain new and useful Improvements in Rotary HeeLTrimmerS, of which the following is a specification.

This invention relates to rotary heel-cutters formed to trim and mold boot and shoe heels; and it has for its object to enable the same tool at one operation to turn and finish the heelseat and the top lift at all parts of the-molded portion of the heel.

To this end the invention consists in a cutter composed of two sections, mounted on a power-rotated arbor and capable of separating, so that the entire width of the cutter may vary to correspond to the variation between the width of the molded portion of the heel at the sides and at the back, the latter being the wider portion in heels of womens boots and shoes in consequence of the increased backward inclination of the rear portion of the heel. The

sections of my improved cutter are provided,

respectively, with a guard for the heel-seat and for the face of the top lift, and said guards are kept in contact with the heel-seat and top lift of the heel by a spring, which normally presses one section toward the other and permits the sections to be separated by the increase in the width of the heel when the side portion passes from and the rear portion is presented to the cutter, all of which I will now proceed to describe and claim.

Of the accompanying drawings, forming a part of this specification, Figure 1 represents a side elevation showing my improved cutter in operation on the side or narrower portion of the heel. Fig. 2 represents a side elevation showing the cutter in operation on the back or wider portion of the heel. Fig. 3 represents a section on line 00 m, Fig. 1. Figs. 4 and 5 represent perspective views of theparts or sections of my improved trimmer.

The same letters of reference indicate the' same parts in all the figures.

In the drawings, a and a represent the sections composing my improved cutter. The sec tion a is rigidly attached to an arbor, b, which is mounted in suitable bearings and rotated by power, while the section a is rigidly attached to a sleeve or collar, 0, which is adapted to move endwise independently on said arbor, and is caused to rotate therewith by a stud,c, affixed to the collar, and a longitudinal groove, 6, in the arbor receiving the stud, the latter having an anti-friction roller, which permits it to move easily in the slot. 7

6 represents a spring which is placed on the arbor and presses the sleeve 0 and cutter-section a toward the cuttersection a, so that normally the two sections are in contact with each other, as shown in Fig. 1. The section a is provided with a lip or guard, 2, which projects over the heel-seat and prevents the upper from touching the cutting-edges. The ends of the cutting-edges next to the guard 2 are formed to mold or shape the heel-seat.

The section ais provided with a beveled guard or rest, 3, for the face of the top lift. The angle formed by the guard or rest 3 and the molded surface of the section a conforms to the angle formed by the edge and face of the top lift of the heel, as shown.

The sections a and a are preferably composed of toothed plates secured together, the plates of the section abeing clamped between a shoulder, 4, and a nut, 5, on the arbor b,while the plates of the section a are secured by screws 6 to the sleeve 0. The teeth t on the proximate plates on the two sections are offset or project outwardly, as shown more clearly in Fig. 5, the teeth on the one section projecting into spaces between the teeth 25 on the other section, so that when the sections are separated or moved apart there will be no break in the cutting-surface.

Operation: The cutter is preferably of such width when its sections are in contact with each other that when the side of the heel is presented to the cutter the guard 2 will bear on the heel-seat and the rest 3 against the face of the top lift, as shown in Fig. 1. As the heel is turned to present its Wider rear portion to the cutter,the section a gradually separates from the section a, as shown in Fig. 2, the guard and rest still maintaining the same relation to the heel and top lift. When the oppositeside of the heel is brought to bear on the cutter,

1. The combination, in a rotary heel-trim- V mer, of two cutting-sections overlapping each other and presenting a convex trimming surface curved to adapt it for the contour of the side of a heel, oneof said sections having a yielding movement, wherebyv the convex, trimmin g;surfaoe is. automatically lengthened to act upon the extended rear portion of the heel, substantially as Bflb, forth.

2. A rotary heel-trimmer composed of two cutting-sections. overlapping. each other, one formed to trim the heel seat and the upper portion of the hee1,, and havinga guard,; 2,

while theother is formed toitrim the lower portion of Z the, heel, and. has a top-liftrest, 3,

one, of said sections having yielding movement, whereby the trimmer is enabled to adjust itself to the varying width of the heel, as set forth.

3. The combination of an arbor, a cutting- .section affixed thereto and provided with a guard formed to enter the groove between the counter and rand or heel-seat of a boot or shoe, and with knives formed to trim the heel-seat and, the adjacent portion of the surface of the heel, a cutting-section rotating with but adapted to slide on the arbor toward and from the other section, and formed to trim the lower portion of the heel, a rest for the face of the top lift attached to the sliding section, and a spring, whereby said sliding section is enabled to conform to the variations in the width of the heel, said sections being formed to over- 5 lap eachother, as set forth.

In testimony whereof I have signed my name to this specificatiomin the presence of two subscribing witnesses, this 2d day of May, 1885.
